Watts spends 23 hours a day in his cell at the Weld County Jail under “Close Watch Protocol,” a technical name for suicide watch. He has no TV. Once a day, he is allowed to go to the common room, where he is alone. In that room is a table with a communal newspaper that he is free to read.

His cell is no less sparse. PEOPLE has learned that the 33-year-old has just two personal effects: a Bible and a photo of his wife and children, 34-year-old Shan’ann Watts and girls Bella, 4, and Celeste, 3 — the same people he allegedly killed.

“He doesn’t have much to do in jail,” says a source who has spoken to Chris.

Chris, who occasionally speaks with guards and can talk to other prisoners, is keeping a low profile as he awaits his eventual trial.

“He sleeps a lot,” the source says. “He can just sit there and look at the picture and read the Bible.”

In an arrest affidavit obtained by PEOPLE, investigators revealed that they had discovered Chris’ affair with an unnamed co-worker, which he initially denied. The document also alleges that he confessed to killing Shan’ann, who was 15 weeks pregnant.

“She loved God, her family and her friends,” Father John Forbes told the mourners. “She was a woman of determination. She had dreams to be fulfilled, and she worked towards to those dreams. She wanted to make a difference. She wanted to be an exceptional wife and mother.”
